Velocity is speed in a direction or speed at an angle. The velocity changes when the speed or angle changes.
Yes. You can consider a vector of being made up of a magnitude (size) and a direction. If any of the two changes, it is no longer the same vector. Alternately, you can also consider a vector (in two dimensions, for simplicity) as being made up of an x-component and a y-component. It is not possible to change the angle without changing at least one of the two components.
Acceleration can change as time changes if there is a change in the velocity of the object. Acceleration is the rate of change of velocity over time, so any change in velocity will result in a change in acceleration.
When the direction of an object changes, its velocity changes as well. Velocity is a vector quantity that includes both speed and direction, so any change in direction will impact the velocity of the object.
Yes, you can have constant speed but change in velocity if the direction of motion changes. Velocity is a vector quantity that includes both speed and direction. So, even if the speed remains constant, if the direction changes, the velocity changes.
The rate of change in velocity is known as acceleration.

The velocity might still change, in the case of a force applied at a right angle to the movement. In this case, since the object's direction changes, its velocity changes.

A change in velocity basically IS a change in motion.

Yes, a change in speed can also be a change in velocity if the direction of the object's motion also changes. Velocity is a vector quantity that includes both speed and direction, so any change in speed or direction will result in a change in velocity.
to keep the angle under which propeller section sees the relative velocity. Because, a propeller essentially is a wing which rotates around an axis parallel to the flight velocity. wings operate best at a certain angle of attack, which is an angle at which wing 'sees' the flow. now, propellers rotate and tangential velocity increases from root to tip. airflow velocity is obviously constant. tangent of angle between relative velocity and prop section is air velocity / tangential velocity. we want angle between propeller section and relative velocity to constant, since tangent changes from root to tip , we need to change angle of propeller section itself.
acceleration is change in velocity.. and velocity constantly changes in circular motion, as the direction constantly changes. This constant change in velocity causes the object to accelerate.
A change in velocity is acceleration, so a accelerometer
Consider velocity as consisting of a speed, and a direction. If any of the two changes - that is, if either the speed or the direction changes - then the velocity changes.
